Co2 laser cutting machine uses co2 glass laser tube as the laser source. It is through 3 reflect mirrors to reflect laser to 1 focus lens and focus the laser to one point so that to cut acrylic wood and other work pieces. The laser goes from laser tube to the focus lens is called laser light path.
The laser beam is focused through the focal lens. The focal lens acts like a magnifying glass and sunlight. For a 55mm lens, the laser beam passes through the lens and converges to the smallest point at about 55mm from the edge of the lens. The laser beam concentrate to the smallest size at this “spot”. Because the lens mount in the focal tube. The question is how to put the material at the optimum location to engrave or cut.
Whenever we want to engrave or cut, we want to have the laser beam focus to the smallest spot and that spot locate at the top surface of the material. Having the smallest spot size will give us the best resolution. the best DPI (dots per inch). The laser machine should have come with a manual height measurement tool. Some machine come with a square piece or acrylic to match to a marker on the side of the focal tube. Other machines come with a feeler gauge that exactly fits between the focal tube nozzle and the top surface of the material.
The normal adjustment method is to place the material on the worktable. And then to move the worktable height such that the top surface of the material is at the focus spot of the laser beam. Use the measurement tool while moving the table to the proper height. Make sure not to move the table too far. You will not want to damage the table surface, material, or the focal assembly.
Most laser machines have a movable table height. It is called up and down table, which is optional. If the table will not move or is already moved to the top, then the focal tube has some adjustment to move/slide up and down about 1.5 inches. First, loosen the focal tube nut (or screw). Second, move the focal tube to the desired height above the material surface. Last, tighten the focal tube nut (or screw). If the machine is equipped with up and down table, it can add auto focus function. In this case, the machine can focus automatically.
One co2 laser cutting machine has many optional parts such as working table,laser power, up&down table,wifi, red light position. Welcome to contact XDLASER for details with your cutting requirements.
